NKJV- Son vs Servant

Consider the word Son, used in John 20:31 and Acts 3:13 of KJV, that
is translated from two different Greek words:
huios and paheece.

John 20 :31
(KJV)

Acts 3:13 (KJV)

But these are written, that ye
might believe that Jesus is the Christ, the Son of God; and
that believing ye might have life through his name.

The God of Abraham, and of Isaac,
and of Jacob, the God of our fathers, hath glorified his Son
Jesus; whom ye delivered up,and denied him in the presence of Pilate, when he was
determined to let him go.

Son - uiJovßHuios; hwee-os;
meaning :a son ;used very widely of immediate, remote child, son

Note the word paheece
has been translated in KJV as Servant referring to Christ :
Matthew 12:18Behold my servant
(paheece),
whom I have chosen; my beloved, in whom my soul is well pleased: I will
put my spirit upon him, and he shall shew judgment to the Gentiles.

The NKJV translated the word into Servant in Acts 3:13, as opposed to
Son:
The God of Abraham, Isaac, and Jacob, the God
of our fathers, glorified His Servant Jesus, whom you delivered
up and denied in the presence of Pilate, when he was determined to let
Him go.The Chinese Union Version also uses the word Servant in this verse.

Considering the context in the verses Acts 3:13; 3 :26; 4:27; 4:30
that Christ was the one ‘sent by God?(Acts 3:26) ‘to heal?and do ‘signs
and wonders?(Acts 4:30), we can say that Servant is the right word translating
paheece.

There is no reason whatsoever to think that the translators of the NKJV and the
Chinese Union version wanted to deny the deity of Christ in Acts 3:13.
